A RADIOIMMUNOASSAY FOR NEUROTENSIN
Clinical Endocrinology, 1981SUMMARYA specific radioimmunoassay for neurotensin has been developed with a sensitivity of 40 pg/ml. Neurotensin‐like immunoreactivity in human plasma shows characteristics similar to synthetic neurotensin on Sephadex G‐25 (f) gel chromatography.

Acta Endocrinologica, 1970
ABSTRACT A number of radioimmunoassay systems have been developed for quantitation of a variety of steroid hormones. Suitable antisera were obtained by immunizing rabbits with steroid derivatives conjugated at various positions to bovine serum albumin. The specificity of the antisera varied directly with the position of conjugation.

Barbiturates: Radioimmunoassay
Science, 1971The development of a radioimmunoassay for barbiturate is described. The barbiturate is made antigenic by coupling it to a protein, bovine gamma globulin. The radioimmunoassay can measure as little as 5 nanograms of barbiturate.

Radioimmunoassay for reserpine
Life Sciences, 1976Abstract Antisera against reserpine have been developed in rabbits immunized with reserpine conjugated to bovine serum albumin. These antisera were used in a radioimmunoassay procedure for reserpine. No appreciable cross-reactivity was observed either with reserpine metabolites or with other drugs commonly used in conjunction with reserpine for the ...

Radioimmunoassay for ribosomes
Analytical Biochemistry, 1972Abstract A radioimmunoassay for quantitating ribosomes is presented. The assay allows for precise, efficient, and rapid estimation of ribosomes in small samples of tissue (50–100 mg).

Abstract The radioimmunoassay for glucagon has established the hormonal identity of this factor and exposed broad areas of its physiology and pathophysiology. While the ultimate importance of glucagon in man remains to be determined, there is little doubt that this previously unexplored area of endocrinology has been one of the major beneficiaries of

Radioimmunoassay for Thymopoietin
The Journal of Immunology, 1976Abstract A radioimmunoassay for thymopoietin was developed that detects thymopoietin concentrations greater than 5 ng/ml. A critical point in development of the radioimmunoassay was preparation of 125I-labeled thymopoietin by the Bolton-Hunter method, since direct iodination of tyrosyl residues impaired the immunoreactivity of ...

A radioimmunoassay for tetrahydrocortisol
Analytical Biochemistry, 1978A radioimmunoassay for urinary tetrahydrocortisol (THF) is described. Antibodies were produced in rabbits against a THF-monohemisuccinate:bovine serum albumin conjugate. The radioimmunoassay procedure involves enzymic hydrolysis of the urine, extraction with ethyl acetate, radioimmunoassay, and separation of free from bound steroid with Somogyi ...
